ARTHUR BEARGEON, OF COMPTON, CALIFORNIA.

GRAVEL-SEPARATOR.

SPECIFICATION forming part of Letters Patent NO. 663,212, dated December 4, 1900.

Application filed March 27, 1900. serial No. 10,315. (No model.)

To all whom it may concern:

Be it known that I, ARTHUR BEARGEON, a citizen of the United States, residing at Oompton, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Sand and Gravel Separators, of which the following is a speci-' fication, reference being had therein to the accompanying drawings.

This invention relates to improvements in car-loaders provided with screens for gravel and the like; and the novelty resides in the peculiar construction and combination of parts, all as more fullyhereinafter described,

shown in the drawings, and then particularly pointed out in the claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which Figure 1 represents a side elevation of my improved screen in position for use upon a fiat-top car. Fig; 2 is a top plan view, and Fig. 3. is a detail view, of one of the screen operating and adjusting devices.

Like letters of reference indicate like parts throughout the several views. 7

In the drawings, A designates a flat-top car of known construction.

Bis a plow havinga substantially V-shaped head portion provided with a clevis D for the attachment of a cable for drawing the plow over the top of the car. 0 is a rectangular frame to which the head or front portion is secured. This frame may be strengthened by brace-bars, as shown. This plow and frame are connected with a rectangular frame D, from the front and rear corners of which rise the standards E, formed at their upper ends with journals or bearings F, in which are mounted the upper bars G of the screens G, one of which is secured upon each side of the device, as shown. Depending from the bars G are the rods 9, secured thereto in any suitable manner. The bars G are each extended rearward and downward, as seen best in Fig. 1, to form crank-arms J, to each of which is connected, in any suitable manner, one end of a chain K, each chain being wound upon a tensions c of the frame C, as shown.

rod L, mounted in the frame D, and in ex- Fast on each of said rods L is a disk M, having a series of openings N, any one of which is adapted to be engaged by a dog or detent O, pivoted on the extension 0 of the frame C, the purpose of the same being to hold the screens at any desired adjustment, according to the size of gravel to be screened. When the rods L are turned, the chains move the crank-arms J, and thereby the lower ends of rods g of the screens either toward or away from the frame.

In operation the flat-cars forming the train are all in line after the manner of acontinuous platform with the sand and gravel upon the top of the cars. The nose of the plow rests flush with the top rear end of one of the cars and into the material, and when the plow is drawn along it pushes the gravel and sand outward, and the sand and smaller gravel-4. e. ,that capable of being pushed or of passing between the lower ends of the screen- .rods and the sides of the platformfall together along with the sand and gravel which passes between the rods of the screens and forms a pile or row of mixed sand and small gravel on each side of the car, while the larger gravel (not passing through between the screen-rods or between the lower ends of the rods and the sides of the platform) is pushed ahead on the platform where, as it works its way to the side of the platform and in front of the plow-frame, it drops off the platform ahead of and in line with the line of mixed sand and gravel alongside of the track and can be removed in any suitable manner.

I claim 1. In a gravel-separator, the combination of a frame, a plow'arranged therein, and screens arranged on each side of said plow and connected with said frame.

2. A car-unloader, consisting of a plow, an outer frame connected therewith, screens connected with said frame on opposite sides of said plow, andmechanism for adjusting said screens, substantially as described.

3. In a gravel-separator, the combination with a car, of a frame resting on the top thereof, a plow carried by said frame, standards rising from the frame on each side of the plow, and screensconneeted with said standards.

4:. In a gravel-separator, the combination 7 with a car, of a plow resting flat upon the same and adapted to be drawn over the car, screens arranged on each side of the plow
